38022580 divided by 503 
The aim is to understand the frequency of 503 in 38022580.

Going ahead to step 1:
503 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 503

On to step 2:
503 can be fit into 38 0 times, resulting in a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 503

Step 3:
If we divide 380 by 503, we get 0 and a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 380 after subtracting 0 from 380.
Grab the next digit (2) from the dividend, add it to 380, then carry on: 3802 / 503

Advancing to step 4:
503 goes into 3802 7 times with a remainder of 281.
The next digit of our result is 7. 
Result so far: 7.0
If we take 3521 away from 3802, we end up with 281.
Fetch the next digit (2) from the dividend, attach it to 281 and continue: 2812 / 503

Step 5:
503 can be fit into 2812 5 times, resulting in a remainder of 297.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we take 2515 away from 2812, we end up with 297.
Bring next digit (5) of the dividend behind the 297 and repeat the process: 2975 / 503

Moving on to step 6:
The number 503 fits into 2975 5 times, leaving a remainder of 460.
The next digit of our result is 5. 
Result so far: 755.0
Subtract 2515 from 2975 to get 460.
Grab the next digit (8) from the dividend, add it to 460, then carry on: 4608 / 503

Let's proceed to step 7:
503 goes into 4608 9 times with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 7559.0
If we take 4527 away from 4608, we end up with 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 503

Step 8:
The number 503 fits into 810 1 times, leaving a remainder of 307.
Write down 1 as next digit of the result. 
Result so far: 75591.0
If we take 503 away from 810, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Let's proceed to step 9:
If we divide 3070 by 503, we get 6 and a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 75591.6
If we take 3018 away from 3070, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
If we divide 520 by 503, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 75591.61
Subtracting 503 from 520 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
The number 503 fits into 170 0 times, leaving a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 75591.61
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 12:
If we divide 1700 by 503, we get 3 and a remainder of 191.
The number 3 becomes the next digit in our result. 
Result so far: 75591.6103
If we take 1509 away from 1700, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Advancing to step 13:
The number 503 fits into 1910 3 times, leaving a remainder of 401.
Record the quotient 3 as the next digit in the result. 
Result so far: 75591.61033
If we take 1509 away from 1910, we end up with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

After the division, we end up with 75591.61033 and a remainder of 0.000401.
